MATLAB: Does the box outline not appear on top of figure

figureMATLABpcolor

The code below gives me a figure with no box outline on top (see attached file). I have tried many things, including "box on" and Clipping off but have not managed to find out how to add the top line (even artificially, if necessary). I'm thankful for any advice!
x=linspace(0,1,201);
y=linspace(0,1,201);
for n = 999
a=zeros(201,4020);      %this is a matrix of size 201 times 4020
  
cellsICC=a(:,202:402);
colorbarOn=1; %1 if want them; 0 if not
[I1,J1] = find(vessels1>0); 
figure
pcolor(x,y,cellsICC)
colormap(flipud(bone));
set(gca,'XTick',[])
set(gca,'YTick',[])
set(gca, 'Box', 'on');
set(gcf,'color','w');
axis square
        if colorbarOn==1
           cbh=colorbar ('eastoutside');
           set(cbh,'YTick',0:1:max(max(max(cellsICC)),2));
        end
view([0 90])
caxis([0 max(max(max(cellsICC)),2)])
shading flat
for i=1:length(I1)
line(x(J1(i)),y(I1(i)),'Color','Red','LineWidth',0.1,'Marker','.')
end
end

Hi Linnea Franssen,
your code example cannot be executed. Nevertheless, did you try to add:
 set(gca,'Box','on');
Kind regards,
